Deep Carbon Cycling Over the Past 200 Million Years: A Review of Fluxes in Different Tectonic Settings

Abstract: Carbon is a key control on the surface chemistry and climate of Earth. Significant volumes of carbon are input to the oceans and atmosphere from deep Earth in the form of degassed CO2 and are returned to large carbon reservoirs in the mantle via subduction or burial. Different tectonic settings (e.g., volcanic arcs, mid-ocean … Read more…

Rock solid insights deepen our understanding of the world

Final year undergraduate student, Madison East is based in the School of Geosciences EarthByte Group, a leading international collaboration between Australian universities, industry partners and centres of excellence. “I began a research scholarship with Dietmar Müller and the EarthByte Groupin the summer of 2016/17 looking at how subduction zones have evolved since the Jurassic,” said … Read more…

Understanding the Deep Carbon Cycle from Icehouse to Greenhouse Climates

Sydney Research Excellence Initiative grant (2017-2018) Research area, key questions, significance, and innovation. The planet is experiencing a major transition from an icehouse climate, one dominated by permanent continental ice sheets at high latitudes, to a greenhouse climate that favours ice-free conditions. Although part of the deglaciation trend is influenced by a natural orbital cycle, … Read more…
